Sets the specified attribute to the specified value. Same as XNVCTRLSetAttribute(). Queries the value of the specified attribute Queries the value of the specified string attribute Set the specified string attribute with the specified string. Queries the valid values for the specified attribute Sets the color conversion matrix Queries the color conversion matrix XNVCTRLQueryExtension() Bool XNVCTRLQueryExtension ( Display *dpy, int *event_basep, int *error_basep ); This function returns True if the extension exists, False otherwise. event_basep and error_basep are the extension event and error bases. Currently, no extension specific errors or events are defined.
